Power Steering Pump: Testing and Inspection
Check the fluid pressure as follows to determine whether the trouble is in the pump or gearbox.
NOTE: First check the power steering fluid level and pump belt tension.
CAUTION: Disconnect the high pressure hose with care so as not to spill the power steering fluid on the frame and other parts.
1. Disconnect the outlet hose (high-pressure) from the pump outlet fitting, then install the P/S joint adapter (pump) on the pump outlet.
2. Connect the P/S joint adapter (hose) to the power steering pressure gauge, then connect the outlet hose (high-pressure) to the adaptor.
3. Install the power steering pressure gauge to the P/S joint adaptor (pump).
4. Open the shut-off valve fully.
5. Open the pressure control valve fully.
6. Start the engine and let it idle.
7. Turn the steering wheel from lock-to-lock several times to warm the fluid to operating temperature.
8. Measure steady-state fluid pressure while idling. If the pump is in good condition, the gauge should read less than 1500 kPa (213 psi). If it reads
high, check the feed line or valve body unit see General Troubleshooting.
9. Close the pressure control valve, then close the shut-off valve gradually until the pressure gauge needle is stable. Read the pressure.
